This is a slightly more flexible implementation of Jdanov's formula, with defaults set to match his parameters. The numerator is the sum of (death counts) in ages 95, 100, and 105. The denominator consists in the sum of the 5-year age groups centered around each of the numerator ages. It probably only makes sense to use this with the default values, however. Used with a single age in the numerator, it is almost the same as `Noumbissi()`

, except here we pick out particular ages, whereas Noumbissi picks out terminal digits.

check_heaping_jdanov(Value, Age, Agei = seq(95, 105, by = 5))

Value | numeric. A vector of demographic counts by single age. |
---|---|

Age | integer. A vector of ages corresponding to the lower integer bound of the counts. |

Agei | integer. A vector of ages to put in the numerator, default |

The value of the index.
